你是否对每天重复单表CRUD
,改mapper.xml
字段已经感到厌烦?
那么快点来整mybatis-plus
代码生成器吧!
首先到官网
并且从github
拉下来最新的代码~
没错,最新的!
当然,除了github
,我们也可以选择gitee
然后用尽你的全力去点clone
------哦!中文是克隆
然后你可以喝杯水
虽然代码拉下来了,但我们还需要使用gradle
加载依赖~
此时我们可以看看README.md
这告诉了我们如何使用
我们按照说明新建一个启动类(当然如果你想新建一个测试类也可以,这不重要~)
如果你是新建的启动类,那么你需要去build.gradle
里找到这些dependencies
注意,这里有两个build.gradle
,我们需要选择这一个
然后把testImplementation
改为implementation
你也可以改你需要的那个,例如mysql
如果你选择新建测试类而不是主启动类,那这步可以不用做啦
然后是启动类

我还简单配置了Controller
和POJO
生成的模板,更易用了
